Pneumatic mechanical chest-abdomen-linkage interaction automatic pressing machine

Abstract

The invention discloses a pneumatic mechanical chest-abdomen-linkage interaction automatic pressing machine comprising a stretcher. Each of two sides of the stretcher is provided with two open grooves. A limiting column is fixedly arranged in each open groove; sleeves sleeve the limiting columns, the side edges of the sleeves are in threaded connection with clamping locks and reverse gear structures, and carbon fiber pull rods are fixedly arranged at the tops of the sleeves. A first operation box and a second operation box are arranged at the top of the stretcher, and the two sides of the first operation box and the two sides of the second operation box are fixedly connected with the ends of the four carbon fiber pull rods in a one-to-one correspondence mode. According to the device, the mode of combining independent chest and abdomen pressing is adopted, and the defects of independent chest and abdomen pressing are overcome; meanwhile, the defect that complications such as rib fractures are easily caused by traditional chest compression is overcome by adopting a chest compression mode of convex block and arc design; an abdomen compression lifting mode is introduced, and the chestand abdomen compression pads adopt springback and negative pressure adsorption devices, so that the chest can be quickly sprung back, the abdomen can be quickly lifted, and the recovery efficiency isimproved.

[0002] Sudden cardiac arrest is the most dangerous clinical manifestation. If it is detected early and treated quickly, many patients can still fully recover autonomous behavior

In the 1950s and 1960s, European and American countries began to propose cardiopulmonary resuscitation technology. Cardiopulmonary resuscitation (CPR) is a rescue treatment for cardiopulmonary arrest. After more than half a century of development, CPR technology has made great progress, but The success rate of resuscitating cardiac arrest is still low, and even survivors often have neurological disabilities of varying degrees

In 2000, the first-step cardiopulmonary resuscitation guidelines were issued internationally. In 2010, the American Heart Association promulgated the "AHA Cardiopulmonary Resuscitation and Cardiovascular Emergency Guidelines 2010". Many patients with cardiac arrest have been rescued by technology. At present, most of them use a single chest compression technique (including manual and mechanical). Due to technical limitations, the success rate of cardiac arrest is still low, especially for middle-aged and elderly people. 80% of them cause rib and sternal fractures, and the complications are relatively high; how to improve the success rate of cardiac arrest rescue has always been an important task in the field of cardiology. A single manual compression of a part of the heart or various mechanical chest compressions Due to technical reasons, deep and effective compressions lead to severe rib fractures and sternal fractures, and the broken ends of the fractures stab the large internal thoracic arteries and veins and lungs, causing serious complications, which directly limits the implementation of chest compression techniques and delays the timing of rescue. , so it cannot meet the clinical rescue needs

[0006] In addition, many chest disease conditions severely limit the implementation of standard chest compression techniques. For patients with clinical chest trauma, sternocostal fractures, hemopneumothorax, thoracic deformity, aortic aneurysm, and post-cardiothoracic surgery, chest compression contraindications Sudden cardiac arrest (SCA) patients cannot achieve STD-CPR cardiopulmonary resuscitation through chest compressions. At this time, alternative passive abdominal compression will play a vital role and is the only cardiopulmonary resuscitation treatment mode. A normally closed chest cavity The environment is broken, the sternum cannot be pressed to form enough force in the chest cavity, the "chest pump" mechanism cannot be realized normally, and STD-CPR cannot play an effective role in resuscitation
